Three additional Sages found exclusively in Crystal are collectively called the Wise Trio (Japanese: ３にんしゅうgroup of 3 men).

In the main series Generation II games, their sprites were edited outside of Japan and Korea, presumably due to Nintendo's policy at the time of removing all religious references in games that they published. This happened again with HeartGold and SoulSilver but only in the Korean version, where the prayer beads were removed, the robes slightly recolored and a red robe on their left shoulder added. Also, their title is changed from Monk (Korean: 중) to Ascetic (Korean: 수행자). This latter edit was not done for other localizations.

Li, the oldest of all Sages who is found at the top of Sprout Tower, is referred to as an Elder. This has become a Trainer class of its own in HeartGold and SoulSilver.

The Sages in Pokémon Adventures

The Sages appear at the Sprout Tower and they are named Chow (Japanese: モクネンMokunen), Nico (Japanese: チンネンChinnen), Edmond (Japanese: エイソウEisō), Jin (Japanese: ソウネンSōnen), Neal (Japanese: カクネンKakunen) and Troy (Japanese: カイネンKainen), respectively known as Peaceful, Mindful, Faithful, Careful, Painful and Thoughtful in the Chuang Yi version. When they see Gold coming to the Sprout Tower, they want to recruit him to be one of them, with the name "Nanyanen" (Awful in the Chuang Yi version). However, Gold refuses as he needs to find the Totodile thief and the Sages have the Bellsprout attack him. The Bellsprout are able to weaken Aibo but get burnt by Exbo.
